Reliability assessment of concrete structures: Advanced stochastic FEM modeling and case studies

摘要

The lecture is focused on a complex methodology for statistical, sensitivity, and reliability analyses of concrete structures. It describes the virtual simulation used on the way from assessment of experimental results to reliability analysis. The whole approach is based on randomization of nonlinear fracture mechanics finite element analysis of concrete structures. Theoretical as well as practical application aspects are presented emphasizing the conceptual framework and key points of solution. Efficient techniques of both nonlinear numerical analysis of concrete structures and stochastic simulation methods of Monte Carlo type have been combined in order to offer an advanced tool for assessment of realistic behavior of concrete structures from statistical and reliability point of views. Degradation aspects, as carbonation of concrete and corrosion of reinforcement, are included too, enabling reliability prediction in time. The significant part of lecture will be devoted to illustrative examples of applications.
